How to reuse sawdust

For every woodworker or DIY-er, nothing comes close to the sense of fulfillment when a project is finally completed. However, when the excitement subsides and the time to clean up your working space comes, you will most likely find yourself in the inevitable mess most DIY and woodworking projects cause. Tools, usually kept properly stashed, are left lying around in disarray, nuts and bolts all over, and all the leftovers from extra materials left unused. One of the most common byproducts of most carpentry projects proves itself quite valuable and it is sawdust. You can use those wood shavings, which seem like a nuisance to clean up, around your house and garden, feed plants, fill gaps and more! Here is how you can reuse sawdust in ways that you probably didn’t even imagine.

1. Fill any Hole

If you’re faced with nail holes or gashes in your wooden wall and furniture and you’re in a need of a quick and easy solution, sawdust and glue is a great and efficient fix up solution. Combine the two until consistency is thick enough and you’ll have the DIY instant filler. Sawdust will solidify glue so that you won’t have nasty streaks running down the wall and it will also match the wood color so the patch isn’t too obvious. Wait for the sawdust-glue filler to dry and and use sandpaper to even the surface.

2. Light up a Fire

Don’t leave the perfect summer outing to the whims of mother nature. If you’re not much of a fire person and you’re struggling to start or keep a fire going, especially if weather won’t cooperate, enlist the help of the DIY sawdust fire starter. Melt some candle wax and mix it with a handful of sawdust while it’s still in liquid form. Pour the mixture in molds, such as old tins and wait for it to harden. The bars you end up with are ready to be tossed into a campfire and thus light it up!

3. Clean up Spills

Even professional handyman do once in awhile suffer accidents. Experience has shown that sometimes two wrongs can make a right though. The mess from a woodworking project can help you deal with the mess from a painting project or other crafting. Sawdust effectively soaks up oil and paint spills, so next time you knock over a tin of paint, just sprinkle some sawdust over the spill. Wood shavings are highly absorbent and will soak up most of it.  Look around the workshop and you will surely find a bucket of sawdust somewhere in there set and ready for that same purpose.

4. Use as an Eco-friendly Herbicide

If you take good care of your garden, you’re probably aware of the beneficial use of wood chips as mulch. But did you know that walnut sawdust is great for getting rid of pesky weeds as well? Due to the chemical juglone contained in walnut wood, it is toxic to most plants, so areas covered with shavings from this sort of wood won’t grow any unwanted greenery. Use it along the driveways or other pathways, but be careful that you don’t sprinkle too close to plants and flowers part of your landscape.

5. Lighten up Cement

Professional contractors have long used sawdust mixed into mortar when erecting cordwood walls. It lightens up the mixture and allows logs to easily bond. It is especially useful to construct lightweight vessels as well. Use this professional technique in your DIY projects involving moisture-loving planters.

6. Clean your Floors

Sawdust can help you clean up the floor of your workshop or garage without the nasty dust. All you have to do is sprinkle some water onto a pile of sawdust and sweep it around any concrete floor via a push broom. It effectively absorbs fine dust and grime which would otherwise go up in the air and stick to your clothes.

7. Feed your Garden

Wood chips are often used in gardening as mulch, so if you save your sawdust, combine it with manure or a nitrogen supplement in order to prevent decay and thus use the mixture to feed your plants healthy and moist.  Mushrooms in specific seem to love Alder sawdust. Another way to incorporate sawdust in your landscape is to cover a dirt pathway and tramp it well to curb erosion and make your walkway even, soft, and fragrant.

8. Use to Pack

Instead of buying packing peanuts or other synthetic materials for shipping or moving items, use wood shavings as a packaging material to fill empty spaces and prevent items from shifting around. Make sure you protect glass and screens from scratching.

9. Litter for Cattle

Animals are often cultivated in booths where wooden sawdust is the perfect source for litter! Compared to straw, sawing has a handful of advantages especially when it comes to dairy cows. Not only the level of absorbency is great, but compared to straw, sawdust is softer and poses no risk of causing injuries, while the presence of sharp straw pieces does.

10. Build various Products

A wonderful use of powdery leftovers of wood produced by sawing is low-density cement-bonded wood fiber composite. It is among the materials professional contractors value the most. It is lightweight with a decent carrying capacity, poriferous, great for insulation and pretty durable. Such composite does not rot nor decay or dissolve easily. This substance is nor rodent, nor termite friendly, insect proof and does not grow fungus. It is know to be environment friendly and does not contain nor emit any toxic or other hazard elements, particles or substances.

11. Make sawdust to snow

Mix the wooden powdery particles with white paint and glue to achieve the effect of artificial snow. Once it dries off you could put it to various applications such as improving your home exterior, interior, decorating presents or any other holiday gifts.

Most of you considered sawdust as waste which only needs to be cleaned after every project but the truth is that sawdust has many useful applications. We hope that you found one of this ways to reuse sawdust interesting and that you will put your sawdust to good use!

    Experienced wood turners take a handful of shavings of the project and hold them against their spinning workpiece to “burnish” the project, leaving a smooth surface & sheen
